Patent Drafting & Illustrations

Patent drafting involves preparation of a patent application detailing various features of the invention and describing the technical effects and advantages of the invention. 

Patent drafting is a vital skill which decides fate of a patent application and facilitates grant without much objections from the Patent Office. A well-drafted patent application allows the applicants and inventors to avoid extended examination, unnecessary expenses, and waste of time, and importantly, allows the applicants and inventors to obtain a desired scope of protection.

Drafting a patent application involves an exhaustive explanation of concepts and ideas that the inventor considers as novel and inventive over existing ideas. It is important to emphasize on the details that are most important for explaining the functionality and/or configurations of the invention. 

Claims form the most important part of a patent application and defines the protection a patentee would receive. Additionally, it is important to prepare drawings of the invention in compliance with legal requirements that correspond to the invention being detailed.

TT Consultants is pioneered in the field of patent drafting and illustrations. We have qualified and experienced Patent Agents and subject matter experts with technical and legal knowledge to assist in preparation of patent applications and drawings.

Our Services

Provisional Patent Application Drafting

We assist our clients in preparing drafts to be filed as a provisional application. One of the aims of provisional application is to be secure the filing date of the application and thus such applications are filed even when the invention is not fully developed. Draft includes description of the invention as much as possible with the drawings and optionally claims as well.

Non-provisional Patent Application Drafting

We assist our clients in preparing drafts to be filed as a non-provisional application. Such applications can be filed directly or after a certain period (generally 12 months) from the date of filing provisional application.

Non-provisional applications involves complete description of the invention, formal drawings, and the claims that define the scope of protection. In contrast to provisional application, a non-provisional application is examined by the Patent Office. 

Patent Illustrations

We assist our clients in preparing high-quality patent drawings that facilitates understanding of the invention described in the patent application. Patent illustrations can be used to increase understanding of the invention and bring out the novel and inventive aspects of the invention.

We prepare patent illustrations as per the legal requirements in various jurisdictions and to avoid any drawing related rejections during examination.

Drafting Claims for New and Continuation Applications

We assist out clients in preparing claims based on several technical, legal, and business parameters. Claims define the protection being granted to the patentee and hence it is important to consider multiple parameters (patentability, competitors, etc.) while drafting the claims. Our team of Patent Agents and engineers have expertise in drafting high-quality patent claims based on client requirements.

Continuation-in-part (CIP) Patent Application Drafting

Continuation-in-part application refers to a related application of a previously filed application. CIP application drafting involves adding new aspects of an invention to a previously filed application.

It is important to analyze what subject matter forms part of the CIP application and how such matter would be linked to the already described invention in the previously filed application. We assist our clients in preparing CIP applications based on new updates and modifications in their inventions.

Claims are not essential while preparing a provisional application. Claims are essential in case of preparing a fresh non-provisional application and when filing a non-provisional application based on an existing provisional application.


Though not essential, it can be beneficial to include a broad model claim in a provisional application as in some jurisdictions, a model claim may set the scope of protection. ​

Filing a provisional application is not necessary. Applicants can directly file a non-provisional application with the patent office.

Provisional application does help to secure a priority date while allowing inventors time to make changes to or refine the invention.

The invention disclosure and the protection sought by the invention may be the same for multiple countries.


A single draft can be filed in different countries. In some cases for filing an application in different countries, the draft may need modified based on current Rules and regulations of that country.

When a patent application is filed, no new matter is allowed to be added in the application. However, the improvement can be filed in form of a CIP (Continuation-In-Part) or Patent of Addition.

Different countries have different rules regarding preparation of drawings. Generally, black and while images with different views are preferred in case of a new device or apparatus.
